GILES A. BEOKWITH, OF WATERFORD, CONNEOTIOUTJ LOCK.

SPECIFICATION forming part of Letters Patent No. 506,461, dated October10, 1893.

Application filed April 8, 1893- Serial No. 469,576. (No model.) i

To all whom it may concern.-

Be it known that I, GILES A. BEoKWI'rH, a

' citizen of the United States, residing at Waterford, in the county ofNew London and State of Connecticut, have invented anew and usefulMortise Lock and Rose, of which the following is a specification. I

This invention relates to that class of mortise locks which havecylindrical cases adapted to be inserted in a hole bored with a bit orauger, and also of a special form of rose or escutcheon that dispenseswith the use of screws being adj ustably interlocked in connection witha companion member of a substantially similar nature and that can beadjusted without removing the knob from the spindle that passestherethrough.

The object of the present invention is to economize space in theconstruction of the lock and at the same time to provide for an easyapplication of the same to a door and requiring a simple formation ofmortise; and also to provide for a simple mode of adj ustment of theroses or escutcheons to compensate for the shrinkage of the door towhich it may be applied.

With these and other objects in view the invention consists of.theconstruction and arrangement of the parts thereof as will behereinafter more fully described and claimed.

In the drawings: Figure 1 is a sectional perspective view of a part of adoor, showing the improved lock and roses or escutcheons appliedthereto. Fig. 2 is a longitudinal vertical section on the line -00,Fig. 1. Fig. 3 is a transverse verticalsection on the line yy, Fig. 1.Fig. 4 is a detail perspective view of the parts of the lockdisconnected from the door. Fig. 5 is a transverse vertical section ofan ordinary form of a knob and knobspindle, showing the improved rosesor escutcheons in connection therewith.

Similar numerals of reference indicate corresponding parts in theseveral figures of the drawings.

Referring to the drawings, the numeral 1 designates the door, in theedge of which is formed an elongated mortise 2, that is constructed byboring a short distance into the door two round holes, spaced apart, andthe intermediate wood removed, and centrally in the said mortise isformed a circular mortise 3 that extends considerable distance into thedoor and slightly in advance of the rear end of the said mortise 3 isformed a transverse circular opening 4 that extends entirely through thedoor. The mortise 2 receives a face-plate 5, that is integrallyconstructed with the outer end of a sectional lock-barrel 6, that isinserted in the mortise 3, and incloses a spring-latch 7, that isarranged to be operated by a knob and spindle, or, if desired, can becontrolled by a key, but it is preferable that a knob and spindle beused.

The latch 7 consists of an engaging end 8 that is arranged to coact witha keeper of suitable form, and has an elongated body 9, with a slot 10extending therethrough, and within the said slot, and bearing againstone termination thereof is a spring 11, whose rear end bears against alug 12, integrally formed with the barrel 6, and by means of the saidspring theengaging end 8 is normally held distended beyond the faceplate 5. 'The rear end of the body 9 is reduced and formed with a yoke13, having lugs at the terminating ends of the said yoke that arearranged to be engaged by an operating arm or cam carried by the spindle14, which is supplied with knobs 15 on opposite sides thereof. ,Oppositeside portions of the barrel 6 are slotted, as at 16, to permit the playof the said yoke of the latch therein, and intermediate of the rearparts of the slots 16 islocated another lug 17, having an opening 18therethrough through which the spindle l4 transversely passes. The armsof the yoke 13 move against opposite sides of the log 18 when the latchis drawn backwardly in the barrel 6. A removable section, 19 is fittedover the body 9 and yoke 13 and held in fixed position by a screw 20that is removably mounted in the lug 12, and this section is formed withan opening that aligns with the opening 18 in the lug 17 to permit thepassage of the spindle entirely through the barrel 6. Thus it will beseen that the latch is arranged in compact form within the barrel 6, andby inserting the latter in the mortise 3 the entire latch is placed inoperative position in the door without forming other slots or recesses,and held in position by two screws, one of which is located at the upperpart of the face-plate 5 and the other at the lower ISO part of thesame, and when the said barrel is in position in the mortise 3 theopening 18 in the lug 17, as well as the opening in the section 19,aligns with the circular opening 4 and located in the center of thelatter. The spindle 14 is then passed through the said opening 18 andthe opening in the section 19, and with the knobs thereon is secured inpositive connection with the door when the latch will be arranged foroperation. In the opening in the section 19, and resting against the lug17, is a collar 21 that projects into the said opening in the saidsection and serves as a bearing for the spindle to hold the latter inproper relation to the remaining parts of the latch, and for operatingthe latter.

To hold the spindle inplace, and for other well known purposes, tworoses or escutcheons 22an'd-23 areemployedof anovelform with animportant advantage. with the'escutcheon23 is a sleeve 24, having anopening 25 extending transversely therethroughthroughwhich the barrel 6extends, and provided at theinner surface of itsterminating endwitlrscrew-threads '26. said sleeveflet fits snugly in the opening 5,and integrally formed with the roseor escutcheon 22 is a collar 27,havingexterior screw-threads 28, and said collar is less in diamete'rthan the sleeve 24: audisso arranged that the'screw threads 2S= thereofproperly engage the'screw-threads-26 of the said sleeve. The outerexposedsurfaces of the roses or escutcheons may besuitablyornamented orembellished with designs, and each of thesameat the center is formedwith a socket-29 that-surrounds the central spindle-opening to receivethe inner opposi n g central collars of the knobs- 15. lhe central partof eaclrrose or escutcheonyaround thesocket 29 therein,is projectedoutwardly or slightly flanged circularly, and on'the rose or escutcheon22, in connection with said 'central flange thereofgare' formed twooppositely-disposed parallel shoulders 30; that are adapted to beengaged by a wrench or otherbifurcated tooltoturn the said rose orescutcheon 22 either to properly fit the collar 27 the1'eof into thesleeve 2e when apply ing thesame to the door, or'to adjust the said rosewhile the knob and spindle are inposi Integrally formed- Th e r tion tocompensate for shrinkage of the door. Bymeans of the construction justset forth, it will be observed that no screws or other fastenings arenecessary to hold the roses or escutcheons in place; and further, thatthe said escutcheons may be readily adjusted without removing either ofthe knobs of the spindle for the purpose stated.

It will be understood that the roses or escutcheons herein set forth maybe equally well employed with any form of knobs, irrespective of theconstruction of the latch or look, and owing to the simplicity andcheapness of construction, as well as the small amount of labor requiredto apply the several parts to a door, avery noveland valuableacquisition to the artis produced.

Changes in the formgproportion,and-the minor details of construction maybe resdrted to without departing from the principle or sacrificing anyof "the advantages of this invention.

Having described "the invention, what is clai1ned--as new'is- Thecombination with a cylindrical lock-casing, 0f-a transversely-disposedsleeve adapted to extendfrom one surfaceofa door to the other andterminate flushwith such surfaces, having a circular diametrical openingtdre ceive the rear end ofsaid lock-casing, and provided at one endwitha fixed roseor escutcheon to bear against one'surf'ace of the' doorand at theother end with an interior-screwthread, asecond rose orescutcheon'removably "attached to theother end of the sleeve and havingan exteriorly th readed collar" to=fit l in the interiorly-threaded endof said sleeve, and a'spindle'extending axially through the sleeve andtransversely through the lock and 'said spindle being provided withterminal knobs, substantially as specified.

In testimony thatI claim the foregoing as it my own I have heretoaiiixed my sign ature in the presence of two witnesses.
